LOUIS SOHLEOHTE, OF ST. LOUIS, MISSOURI.

SHUTTER-.FASTENER.

SPECIFICATION forming part of Letters Patent No. 273,164, dated February 2'7, 1883.

Application flled December 4, 1882. (No model) i To all whom it may concern:

Be it known that I, LOUIS SCELECHTE, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Shutter-Fastenings, of which My invention relates to a shutter-fastening that can be operated to unt'asten theshutters from the outside by means of a stream of water, in case of fire, from the hose of a fire department; and my invention consists in the special construction of the device, as hereinafter fully described.

Referring to the drawings, A A represent the shutters, and B their hinges.

G is a latch pivoted by one end to the inside of the shutter A. Its free end is sustained by a keeper, D, secured to the inside of the shutter A. The keeper is sufficiently long to allow the latch to be raised, as shown in Fig. 5 and by dotted lines, Fig. 2.

E represents a catch secured to the inside of the shutter A, near the edge thereof, which receives the'free end of the latch O ,*thus holding the shutters in their closed posit-ion. When the latch is raised, as before mentioned, it is disengaged from the catch, allowing the shutters to swing open.

Secured to the latch O is a flat thin plate, F, by means of a neck, G, extending through a semicircular slot, H, in the shutter A, the plate thus being on the outside of the shutters, with a fiat side down, as shown, where it can forth.

be operated upon to raise the latch, unfasteniug the shutters, by a stream of water, in case of fire, from the hose of a fire department. When the latch is thus raised the shutters will spring slightly open, giving an opportunity for a stream of water to be directed between them, which will force them open.

I represents a pin secured to the free end of the latch and projecting inward, by which the latch can be raised from the inside of the shut- .ters.

I am aware that it is not new broadly to raise the latch of a shutter-fastening from the 7 to the shutter A, and engaging with-the free endof the latch, flat plate F, with neck G, secured to the latch G, and semicircular slot H in the shutter A, through which the stem of the plate F passes, all substantially as and for the purpose set forth.

2. In a shutter-fastening, the combination of latch G, pivoted by one end to the shutter A, keeper D, secured to the shutter A, to sustain the free end of the latch, catch E, secured in the shutter A, and engaging with the free end of the latch, plate F, on the outside of the shutter, and having a neck, Gr, secured to the catch 0, semicircular slot H in the shutter A, through which the stem Gr passes, and inwardprojecting pin I on the free end of the catch G, all substantially as and for the purpose set LOUIS SOHLEOHTE.
